ESA Contribution rate & Permanent health insurance

Hello,

Please could you advise on the following:

recently my ESA support group contributory rate has been reduced by the DWP from £109 p/w to £27.10 after I informed them voluntarily at a compliance interview I was receiving permeant health insurance remuneration on a monthly basis they have said this is classified as a pension income? I completely disagree with this due to the following reasons:

1- My employer sky has setup the group income protection directly with the insurer Unum
2- Sky are the policy holder not myself
3-The monthly remuneration is paid directly to sky (not myself) who then forward it to me as a continuation of my salary therefore I feel that I should still be entitled to my contribution remuneration from DWP as this is based on my NI contributions
4-I am still employed by my employer but on long term sick
5- My contribution pension & my defined pension have not been touched by me so how can the DWP classify my permeant health insurance as income


I am subject to regular insurance reviews 4 times a year and have even seen Occupational Health Consultants who have confirmed to my employers and the insurers that I am unfit for work. This also means that my NI contributions are fully paid therefore my ESA contribution sum should not be reduced as the DWP have done

Thank you
